It is possible to assemble and raise the tower above ground in response to the wide variety of steel tower root opening dimensions that vary depending on the size and type of the tower, and to raise any leg of the tower using a horizontal lateral load that acts on the top of the tower. This invention relates to a steel tower hoisting device that absorbs loads even if they are applied and enables safe hoisting work.

安定となり、ひいては転倒する危険性すらある。 The root opening dimensions of steel towers vary widely depending on the scale and type of tower. Therefore, conventional steel tower raising devices are designed and manufactured on a case-by-case basis within a range that corresponds to changes in the root opening dimensions of the steel tower. Naturally, therefore, it lacks versatility and cannot be used with different scales and types of steel towers. Also,
Conventional tower hoisting equipment mainly focuses on vertical loads when hoisting steel towers, and does not take horizontal lateral loads into account. Therefore, if the lifting load based on the overturning moment due to the horizontal lateral load exceeds the vertical load from the tower or overhead wire at the anchorage point of each main leg member of the steel tower, the tower and the tower hoisting device will become unstable and eventually fall. It's even dangerous.

よつてロツド７４は下降する。 Reference numeral 7 denotes a load cylinder for pulling down the steel tower, which is attached to the upper part of each of the main lifting columns 11. As shown in FIG. 3, oil hoses 72 and 73 are connected to the upper and lower parts of the cylinder 71 of the load cylinder 7, and pressure oil is supplied to the cylinder 71 by a single hydraulic unit (not shown). controlled.
In this way, the hydraulic unit operates so as to always generate a constant tower pulling load regardless of the stroke position of the rod 74 of the load cylinder 7. The lower end of the rod 74 and one end of the tower pulling beam 2 are connected to the sheave 7 fixed to the plate 11A of the main column 11.
5 and are connected by a wire rope 76. Therefore, as the tower pulling beam 2 rises, the rod 74 descends.

とはない。 The steel tower pulling load T is the steel tower to be assembled due to the horizontal lateral load.
It is set to a value that exceeds the maximum lifting load T' of A'. Therefore, the lifting load applied to one end of the tower pulling beam 2 from the upper part of the steel tower A' to be assembled via the tower main leg member gripping means 5 and the tower attachment beam 4 is offset by the tower pulling load of the load cylinder 7. Ru. Therefore, one end of the tower lifting beam 2 will not be in the lifted state.

ることができるという効果が得られる。 As explained above, the present invention adjusts the separation distance of four sets of lifting frames in two orthogonal axes directions by adjusting two telescopic tower lifting beams and two sets of tower mounting beams, and further sliding the tower mounting beam and the tower main leg gripping means in response to a change in the root opening dimension of the steel tower main leg, and
By absorbing the lifting load with a load cylinder connected to one end of the tower lifting beam via a wire rope and a sheave, the lifting load can be constantly adjusted to the root opening dimensions of the tower, which vary widely depending on the scale and type of the tower. It can be used for raising steel towers from 66KV to 275KV, and the lifting load is offset by the tower pulling load, so the tower raising equipment will not become unstable and the lifting work will be easier. This has the effect of being able to carry out these tasks safely.
